Calibre does a fine job of telling me if a particular title is on the Kobo or "Card A", but it thinks
every SD card is card "A" (versus "B", "C", etc).
It would be Really Nice(tm) if Calibre could differentiate automagically (and display it), but failing that, I'd be fine with doing a custom column and populating it if there was a way to distinguish between SD cards from within Calibre, so I could store different genres to different cards (Tech vs Reference vs SciFi vs ...).
If Calibre can already do that, could some kind soul point me at instructions/directions?
Thanks...
